Definitions

  • the invention relates to a steering wheel with a steering wheel rim, a hub and at least one steering wheel rim and hub connecting spoke, wherein Steering wheel rim and / or spoke a skeleton, one surrounding the skeleton Foaming or extrusion coating as well as one around the foaming or Overmolded shell and have at least one decorative element or has.
  • Decorative elements with special surfaces on the steering wheel rim, e.g. Wood, Aluminum or carbon fiber. Such decorative elements are often included a leather covering of the steering wheel rim combined.
  • a steering wheel with such decorative elements is e.g. in DE 298 03 133 U1 described.
  • the decorative element used there extends in the Cross-section over an angle of approximately 90 ° in the circumferential direction of the steering wheel rim. It is via a snap-in connection with one in the foam surrounding the Steering wheel skeleton anchored component connected. This construction requires a complex injection molding tool for the production of the foam.
  • the object of the present invention is to provide a steering wheel with simple, inexpensive and flexible way to provide decorative elements.
  • This task is achieved with a steering wheel of the type mentioned above solved that the decorative element directly with at least one locking element the shell is connected. Since the decorative element is attached to the shell and not in the foam or encapsulation, the injection mold for the Foaming or extrusion coating can be designed much easier than after mentioned prior art.
  • the latching with the shell also offers that Advantage that the decorative element is less expensive and with a relatively low Self-stability can be established because of the grip and strength of the steering wheel rim or the spoke can be determined by the shell.
  • a shell that surrounds the encapsulation or encapsulation of the skeleton enables a modular structure of the steering wheel and makes it easier in this way
  • Locking provides a quick and secure method of attachment of the decorative element. Since the decorative element does not have the function of the bowl on the Must take over his seat is a relatively low weight sufficient. A latch is therefore for the loads that occur, too for vibrations, sufficient.
  • At least one opening or, more generally, a recess is provided, into which the latching element projects, whereby the decorative element is locked to the shell.
  • Openings with a small cross-section are sufficient to create a decorative element to fix.
  • the foam coating or extrusion coating preferably has a recess in which the locking element extends.
  • a recess in which the locking element extends.
  • the shell advantageously surrounds the skeleton in the circumferential direction Completely. So both the desired diameter of the steering wheel rim or the spoke as well as the general grip by diameter and Material of the shell can be specified.
  • the decorative element can, seen in cross section of the steering wheel rim, on the Border the shell radially on the outside, i.e. the decorative element forms a kind second, outer shell, which increases the positional stability of the decorative element.
  • the shell preferably consists of an upper shell and a lower shell, which are connected at their edges.
  • the top shell and Lower shell are connected to each other by a snap connection.
  • the decorative element is directly on the shell supports, since in this case the decorative element itself is not too high Must have inherent stability because it is carried by the shell. This reduces the cost of producing the decorative elements.
  • leather is provided which surrounds the shell, and it is envisaged that the edges of the leather are at least partially clamped between the decorative element and the shell. In the area of the decorative element, there is therefore no need for Sewn or glue leather coverings as they pass through the decorative element Clamping can be fixed.
  • the locking element is preferably integrally formed on the decorative element, which allows inexpensive production.
  • the decorative element can but also from a carrier on which the locking element is integrally formed, as well as a decorative surface, e.g. made of wood veneer, imitation wood, aluminum or another material.
  • Decorative element can also be made entirely of metal.
  • the locking element of the decorative element e.g. as To design recess in the decorative element and about a projection or one Form locking hooks on the shell.
  • FIG. 1 shows a steering wheel 10 according to the invention, with a hub 12, a steering wheel rim 14 and spokes 16, which the steering wheel rim 14 with the Connect hub 12.
  • a hub 12 a steering wheel rim 14 and spokes 16 which the steering wheel rim 14 with the Connect hub 12.
  • Connect hub 12 a steering wheel rim 14 and / or on the spoke 16
  • Decor elements 18 arranged.
  • the number and arrangement of the decorative elements 18 chosen purely as an example, the decorative elements can be placed anywhere the steering wheel rim and spoke can be placed in any number.
  • FIG 2 shows a section through the steering wheel rim along the line I-I or by a spoke along the line II-II in Figure 1 and illustrates the Structure of the steering wheel.
  • This skeleton 20 is surrounded by a foam 22, which e.g. made of PUR exist and applied to the skeleton in a known foaming process can be.
  • the layer designated 22 can also consist of one Thermoplastics in the injection molding process or consist of an expandable PE or PP.
  • the foam is surrounded by a shell 24, which is shown in FIG Example consists of an upper shell 26 and a lower shell 28.
  • Top and Bottom shell are here at their edges with each other via a snap connection 30 connected, but they can just as well be glued or by another known technology to be connected.
  • the upper shell 26 has one Breakthrough 32 on. Additional, decorative elements can be attached to Breakthroughs, not shown, may be provided. It is also possible to have several Provide openings for fastening a decorative element. On average through seen the steering wheel rim or the spoke, the decorative element 18 is therefore from placed radially outside on the shell, so that there is a double layer structure results.
  • the decorative element 18 has a latching element 34, which is preferably is integrally connected to the decorative element 18.
  • the locking element 34 consisting of two flexible hooks, protrudes through the opening 32 and engages behind the upper shell 26. In the foam 22 there is one at this point Recess 36 provided.
  • the locking element 34 can be any known Be kind.
  • the steering wheel rim 14 or the spoke 16 are in this embodiment surrounded with a leather covering 38, which is under the decorative element 18 is interrupted.
  • the edges 40 of the leather are between the upper shell 26 and the decorative element 18 clamped, so that in the area of the decorative element 18 further attachment of the leather covering 38 can be omitted.
  • the steering wheel according to the invention is assembled as follows. First, as described, the steering wheel skeleton 20 with the Foaming 22 provided, then the lower shell 28 and the Upper shell 26 arranged around the foam and with each other via the Snap connection 30 connected. In the following step, the leather covering 38 mounted and in places outside the decorative element 18 in a known manner closed. Then the decorative element 18 with its locking element 34 inserted into the opening 32 and locked with the upper shell 26 through reaching behind the locking element 34 on the back of the upper shell 26, the edges 40 of the leather covering 38 between the decorative element 18 and the upper shell 26 are clamped.
  • the decorative element 18 itself can be constructed from two sections, a plastic carrier 42, on which the locking element 34 is integrally formed, and a surface component 44 with an optically high-quality surface material.
